The known health effects of UV The skin produces a dark-coloured pigment, melanin, as a shield against further damage from UV radiation. The darkening provides some protection against sunburn: a dark tan on a white skin offers a sun protection factor of between 2 and 4. However, it is no defence against long-term UV damage such as skin cancer.

Information for the Melaninated Being As melanin is a complex living molecule abundants in Africans it aids protecting Africans from ultraviolet rays-and like dark clothes are not worn in the sun due to its ability to hold heat attracting sun rays, the analogy is the same for melanin dominant beings, the sun is drawn to them creating amazing things.itamin D-Is needed for calcium absorbtion and this is converted from the sun's UV rays and us melaninated beings require at least 20 minutes daily sunlight on at least the face and arms (preferably not washing until at least 30minutes after to allow absorbtion into the bloodstream).

Can't hold a drink or cope with pain? Blame the colour of your eyes The lack of melanin also made people's skin lighter, and fair skin is better at making vitamin D, vital in northern climes as there is less sunlight, which the body needs to produce the vitamin. Blue eyes also filter out less light, so can see a little better in weaker sunshine.

Melanin Like all good sunshades, the umbrellas in our skin are darkly colored. The dark pigment in our skin, called melanin, is typically black or brown. This protein is produced by special cells, called melanocytes, which are located in the lowest level of our epidermis (the surface layer of our skin, Figure 1). 1  MANUFACTURING MELANIN (Figure 1): Melanin is the pigment primarily responsible for our skin color. Melanin is produced in special cells, called melanocytes, located in the lower layer of our epidermis (the surface layer of our skin). Melanocytes themselves are not the umbrellas of our skin. They merely produce the melanin for our skin, in the form of tiny granules called melanosomes.

How Melanin Production in Skin is Related to Skin Color? The main function of melanin is to provide pigmentation mainly to the skin, hair and iris of the eye. In addition melanin is important in protecting the skin from ultra violet rays of the sun which can be damaging. This is why albinos are highly susceptible to skin problems such as sun burns caused by UV rays.elanin is produced in the skin in cells known as melanocytes and through a process called melanogenesis. There exist different subtypes of melanin which are found in different people and different parts of the body.

Home Remedies for Skin Pigmentation Sometimes, the melanin production goes awry; either too little or too much melanin is produced causing skin pigmentation disorders. These conditions make the skin appear lighter or darker than normal, or blotchy and discolored. Too much melanin causes hyperpigmentation and too little melanin results in hypopigmentation.

Berries: Small But Mighty In common usage, “berry” refers to any small edible fruit—usually juicy, colorful, sweet or sour, and without a pit, though it may have small seeds. This is how we are using the term. However, the botanical definition of berry is a fleshy fruit derived from a single flower and containing a single ovary. Botanically speaking, tomatoes, avocados, eggplants, grapes, watermelons, and bananas are all berries, whereas blackberries, raspberries, mulberries, and strawberries are not.

How to Produce Melanin in Your Body The sun can be harmful whatever the temperature, so it is possible to produce melanin in the winter, but you'l still need to be careful with exposure to direct sunlight. UV rays can also get through clouds on overcast days. It can also be even worse in snow as the white snow reflects UV rays up as well as down.

How can one remove sun tans and lighten the skin back to its original color? People who have light skin have less. Here's how melanin makes your skin burn or tan: 1  Your body normally makes melanin to try to protect the deeper layers of your skin from damage.  When your skin gets damaged by the sun's rays, it makes even more melanin to try to protect your skin from being damaged even more. That causes the skin to change color:

5 Reasons You're Missing Vitamin D During Menopause People with dark skin have more melanin, which reduces the skin's ability to make vitamin D from sunlight. Although these people are less likely to get a sunburn, they are also less effective at turning sunshine into vitamin D, leaving them at more risk for a vitamin deficiency.

Skin Pigment Disorders Skin color is determined by a pigment (melanin) made by specialized cells in the skin (melanocytes). The amount and type of melanin determines a person's skin color. Melanin gives color to the skin, hair, and iris of the eyes. Levels of melanin depend on race and amount of sunlight exposure. Sun exposure increases melanin production to protect the skin against harmful ultraviolet rays. In addition, hormonal changes can affect melanin production.

How Albinism Works Ultraviolet rays can damage DNA and other cell parts, but melanin absorbs the rays. For people with albinism, there are not enough melanosomes available in skin cells to fight off the harmful rays. The resulting lack of melanin leaves the skin vulnerable to sun damage, increasing the risk of sunburn and skin cancer.

How Sunburns and Sun Tans Work So, now that we know all about the skin we can start to actually understand tans and sunburns. When you get a tan, what is actually happening is that the melanocytes are producing melanin pigment in reaction to ultraviolet light in sunlight. Ultraviolet light stimulates melanin production. The pigment has the effect of absorbing the UV radiation in sunlight, so it protects the cells from UV damage.
